Inferring temporal priors can help alleviate occlusion. Methods involving volumetric fields
[1]} use temporal information as the field is
sequentially updating with new information, instead of fully being reinitialized as per our method.
The percentage of pixels recovered is also dependent of the side cameras configuration.
In our clinical case, the camera setup is constrained by the C-arm design and
the disparity between the X-ray source and the two RGBD cameras is low. A higher
disparity would lead to less occlusion in at least one of the cameras. Even with our
constrained and difficult clinical setup, the results are extremely promising
and we are convinced the work could also be easily extended to less restrictive
settings. A potential application is Industrial Diminished/Mediative Reality
where workers wearing a HMD with two cameras placed on its side (with a higher
disparity than our setup) could see their viewpoint synthesized with their hands
in transparency.
